World - Will the Race for Electric Vehicles Endanger the Earth's Most Sensitive Ecosystem?
Materials needed to make the batteries for electric cars and other clean technology is driving interest in deep-seabed mining, and scientists fear the cost to the ocean will be steep.
The internal combustion engine had a good run. It helped get us to where we need to go for more than a century, but its days as the centerpiece of the automotive industry are waning.
As countries work to cut greenhouse gas emissions, electrification is stealing the limelight.
While there’s still a long road ahead — electric vehicles only accounted for 3% of global car sales in 2020 — EV growth is finally climbing. From 2010 to 2019 the number of EVs on the road rose from 17,000 to 7.2 million. And that number could jump to 250 million by 2030, according to an estimate from the International Energy Agency.
The growing demand for electric vehicles is good news for limiting climate emissions from the transportation sector, but EVs still come with environmental costs. Of particular concern is the materials needed to make the ever-important batteries, some of which are already projected to be in short supply.
“Climate change is our greatest and most pressing challenge, but there are some perilous pathways to be aware of as we build out the infrastructure that gets us to a new low-carbon paradigm,” says Douglas McCauley, a professor and director of the Benioff Ocean Initiative at the University of California Santa Barbara.
